Tissue Select Feature
NOTE
The high frequency handpiece operates within a frequency range and
36 kHz is a representative value. See the “Technical Specications” on
page A-3 for the frequency range.
Handpiece Congurations
The CUSA Clarity system includes a high frequency handpiece.
Handpiece Tips
A variety of handpiece tips are available.Tips vary in internal diameter and
length. For information on the tips available, see “Tip Specications” on
page A-2.
Tissue Select
®
Feature
The Tissue Select
®
feature allows the surgeon to maintain a high
fragmentation rate while increasing selectivity and control at the surgical
site.
The benets of Tissue Select are:
• Gives surgeon greater control and precision when resecting near
critical structures
• Enhances tissue selectivity while maintaining fragmentation
capability. The power to the site is limited while strength and efcacy
in tissue removal are still provided.
• Provides maximum tissue selectivity
• Gives surgeon superior tactile feedback
Fragmentation
Fragmentation occurs when the vibrating tip comes into contact with
tissue. As the tip begins to move toward tissue, it accelerates, then
impacts and penetrates the tissue. The acceleration, impact, and
penetration produce a combination of direct mechanical forces and
hydrodynamic pressures that burst cells.
Several variables affect the fragmentation rate. Most are functions of the
CUSA Clarity system:
• Amplitude (tip excursion—the total distance the tip travels): greater
amplitude results in greater fragmentation rate
• Aspiration has several functions:
